Officials say the remaining wreckage of United Flight 93 will be returned later this year to the Pennsylvania memorial marking where it crashed in the 9/11 terrorist attacks.

Flight 93 National Memorial Superintendent Stephen Clark says the wreckage will be buried in a restricted area of the Shanksville park that's accessible only to loved ones of the victims.

President of the Families of Flight 93 Gordon Felt says his group requested a final search of the debris to see if there were any human remains or personal items in the wreckage.

Clark says workers found a number of items that will be added to the memorial collection, including an orange passenger call button.
